This opens a Zip code field. If I enter a Zip code manually a list of providers is shown. If I set the value with the script the list is not shown. So I am trying to simulate keypresses, but it is not working.

var create = document.getElementById('ctl00_Main_TVL_ctl00_Nav_ctl00_AddLineup');
create.click();
setTimeout(function(){
    var broadcast = document.getElementById('broadcast');
    broadcast.click();
    setTimeout(function(){
        var zip = document.getElementById('zipEntryInput');
        zip.dispatchEvent(new KeyboardEvent('keydown',{'key':'50'}));
    }, 2000);
}, 2000);
